General Description
The RTQ2963 is a 3.5A, high-efficiency, peak current mode
control asynchronous step-down converter which is
optimized for automotive applications. The device operates
with input voltages from 4V to 60V and is protected from
load dump transients up to 65V, eases input surge
protection design. The device can program the output
voltage between 0.8V to VIN. The low quiescent current
design with the integrated low RDS(ON) of high-side
MOSFET achieves high efficiency over the wide load range.
The peak current mode control with simple external
compensation allows the use of small inductors and
results in fast transient response and good loop stability.
The wide switching frequency of 100kHz to 2500kHz allows
for efficiency and size optimization when selecting the
output filter components. The ultra-low minimum on-time
enables constant-frequency operation even at very high
step-down ratios. For switching noise sensitive
applications, it can be externally synchronized from
300kHz to 2200kHz. The build-in spread-spectrum
frequency modulation further helping systems designers
with better EMC management.
The RTQ2963 provides complete protection functions such
as input under-voltage lockout, output under-voltage
protection, output over-voltage protection, over-current
protection, and thermal shutdown. Cycle-by-cycle current
limit provides protection against shorted outputs, and softstart
eliminates input current surge during start-up. The
RTQ2963 is available in WDFN-10L 4x4 and SOP-8
(Exposed pad) packages.
